Choosing the right rock crusher for reduction of material is based upon

  • The crushing characteristics of your source material
  • The average gradation of your source material
  • The volume of final product you want to produce
  • The size ranges of your final products
  • The target percentages of each size range
  • Knowledge of what equipment is available and its function
  • Balancing all the steps in the process
  • Common sense
Buying used rock crushers has several advantages, especially from the United States
  • A used rock crusher will cost much less than new and still do the same job
  • Used older rock crushers are normally simpler in design and technology
  • Were made with quality materials and experienced craftsmen
  • Used rock crushers made in the USA meet NAFTA and other Free Trade requirements for importing duty-free.
  • Typically run at slower speeds requiring less horsepower and bearings lasting longer
  • Easier to work on by workers with less training and specialized tools
  • Many older rock crushers are still doing a good job after 60 years.
Many new crushers run at higher speeds, require more horsepower, weigh less than the comparable sized older crushers, and their useful life is not as long. Today the demand worldwide for used crushers made in the United States exceeds the available supply. That is especially true for Nordberg, Symons, Cedarapids, Universal, Pioneer, Eagle and Telsmith crushers.
